Cisco FPR – Re-image from FTD to ASA Code
KB ID 0001766 Problem Note: This procedure is to re-image a Cisco Firepower device from FTD to ASA code, (in this example a Cisco FPR 1010). Why would you want to do this? Well to be frank FTD is bobbins, so if you have a device running FTD code you might want to ‘convert’ it to ASA code.

Cisco Catalyst 9200 / 9300 DNA Licensing
KB ID 0001750 Problem I get asked this at least once a month, “What’s the score with this DNA Licensing?” It took long enough for everyone to get used to Lan Base, IP Base, and IP Services! The cynic in me would say, Cisco have learned from Meraki that selling subscription licences is much better than selling products that you don’t get any recurring revenue from. But I’ll try an give you the short answer...
